CHARLES P. HAVLEY, OF NEW YORK, N. Y.

METALLIC RAILROAD-TI E.

SPECIFICATION forming part of Letters Patent No. 379,576, dated March20, 1888.

Application filed Not'ember 10, 1887. Serial No. 254.755.

To all whom it may concern.-

Be it known that 1, CHARLES P. HAWLEY, of the city, county, and State ofNew York, have invented a new and useful Improvement in MetallicRailroad-Ties, of which the follow ing is a full, clear, and exactdescription.

My invention relates to metallic railroadties, and has for its object toso improve the construction of the metallic tie described in applicationfor patentallowed to myself August 30, 1887, as that the tie may beeasily withdrawn from under the track and replaced without disturbingthe movement of the rolling-stock, and wherein the tie willofferaperfeet form for strength and lightness, and to be held securelyby the ballast.

The invention consists in the construction and combination of theseveral parts, as will be hereinafter fully described, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a perspective view of the tie, illustrating onerail-supporting plate in position. Fig. 2 is a perspective View of ablank for use as a brace; Fig. 3, a perspective view of the finishedbrace. Fig. 4 is a side elevation of a track supported upon the improvedtics, illustrating one tie in position for withdrawal.

The object of the present invention, as aforesaid, is to improve theconstruction of the metallic railroad-tie allowed to myself August 80,1887. By reference to the said allowed application it will be observedthat the rail is supported continuously by bridging from tie to tie,passing the stepped ends of the bridge through suitable openings in theweb of the tie, and bolting the same. Now it is obvious that when arailroad-track has been laid in that manner, if it becomes necessary toremove one of the ties it cannot be done without much labor, time, andexpense. To 0bviate this trouble is the purpose of the pres- (No model.)

The body A of the tie is made from a beam of rolled T-shaped iron out orsawed to the properlength,which beam may be of any original length. Neareach end in the web a of the tie-body, when in the normal cold state, inthe upper edge of said web, a T-shaped recess, a, is out or otherwisemade, adapted to accommodate the rail-supporting plate or bar,hereinafter described. The recess in the web may be positively cut tothe actual gage of the track, all shrinkage having previously takenplace. The end braces, D, are also cut from cold metal and in the shapeillustrated in Fig. 2,Which is substantially rectangular, a rightangularrecess, (1, being cut in one lower corner,while in the blank a series ofapertures,

two edges separated by the aforesaid recess. The blank is now pressed ormolded to the proper shape, which is accomplished by bending theapertured edges at right angles to the body upon the dotted lines shownin Fig. 2, whereby the apertured flanges d" d are obtained. Y

The braces D are employed at each side of the web, the vertical flangesbearing against the web, the horizontal flanges resting upon .the base.In locating the said braces the straight vertical face of each is madeto align the side walls of the vertical portion of the web-recess a, theflanges being upon the outer side and the upper end of the verticalflanges said recess a.

It will thus be observed by reference to Fig. 1 that a space is obtainedbetween the smooth contiguous faces of the braces D equal in width tothe width of the Vertical portion of the recess a, and that the tops ofthe braces upon opposite sides of the web and the bottom wall of thehorizontal portions of the said recess a are in the same plane. Thebraces are secured in position by passing rivets or bolts through theaperture in the opposing vertical flanges and through the web, and alsothrough the apertures in the horizontal flanges and through the base ofthe tie.

The T-shaped supporting plates or bars B can be made of any lengthoriginally, and may embrace any number of ties, thus making a lperfectcontinuous support for. the rail; or

d, are produced parallel with and near thein alignment with thehorizontal portion of they can be cut or sawed into sections the widthof the tie, and not act as a support between the ties. V

The horizontal portions of the recess a are of a depth equal to thethickness of the flanges of the supportingplates, and the verticalportions of the recess are preferably of a depth equal to one-half thedepth of the vertical web of said plates.

In the lower edge of the vertical member of the rail support or bar B,where it is adapted to engage the web of the tie, a slot, 1), is cut,preferably of half the depth of said member, as shown in Fig. 1. Therail-supporting plates are not adapted to be fastened to the tie, beingheld in connection therewith by causing the vertical portion of therecess a and the recess b to interlock, whereby the horizontal member oftherail-supporting plate is made to bear at the under side upon thebottom walls of the horizontal portion of the said recess a, the I webof the said supporting-plate being projected down and held between thebraces D. 1 When so positioned, the upper surface of the supportingplate or bar is flush with the upper surface of the tie.

The web of the tie is supported and strength- I ened centrally upon eachside by two abutting braces, O, secured in like manner to the braces D,and differing only from said braces, inasmuch as the bodies of thebraces C are triangular instead of rectangular.

At each side of the recess a apertures a may be made in the web, throughwhich the railclanips heretofore secured to me can be bolted, which,when the rails are placed upon the supporting-plate, clamp the saidrails, fastening them down and also the plate.

With this construction, when it becomes necessary to remove a tie, itcan be accomplished as easily and quickly as at present with theordinary wood tie and in the same way, as it is obvious that, therail-supporting plate or bar not being fastened to the ties, by removingthe rail-clamps and excavating beneath the tie sufficiently, as shown inFig. 4, it drops free from the rail-supporting plate or bar, and thencan be readily pulled out endwise from under the track and replacedagain, while the rail and rail-supporting plate or bar will retain theirposition, the neighboring ties not having been disturbed. Thus thetravel of the rolling-stock is not delayed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, i

1. The combination,with,a metallic tie having a vertical central webprovided with a T-sha'ped notch, of aT-shaped rail-supporting plateadapted to rest upon said web, substantially as shown and described.

2. The combination, with a T-shaped metallic tie having its web providednear the ends with T-shaped notches, of T-shaped railsupporting platesnotched to interlock with the notches in the web,substautially as shownand described.

3. A T-sh aped metallic railroad-tie having its vertical web providedwith T-shaped notches near the ends, and spaced aligning braces oppositeto said notches having their upper edges flush with the base of thehorizontal portion of said notches, substantially as shown anddescribed.

4. A T-shaped metallic railroad-tie having its vertical web providednear the end with T-shaped notches, and aligning braces opposite saiduotches,spaeed to have their opposing sides flush with the verticalportion of the notches and their upper edges flush with the base ofthehorizontal portions of said notches, substantially as shown anddescribed.

5. The combination, with a T-shaped metallic railroad-tie having itsvertical web provided near the'end with T shaped notches, and aligningbraces opposite said notches, spaced to have their opposing sides flushwith the vertical portion of the notches and their upper edges flushwith the base of the horizontal portion of said notches, of T-shapedrailsupporting plates notched to interlock with the notches in theweb,the vertical member of said plates being clamped by the spacedbraces, substantially in the manner and for the purpose herein setforth.
